parallel. It is therefore impossible for them u to tip towardeach other behind the binding post and away-from"eachrotherin' front of it, and thus impossible to spring the sheets from the binder. The parallel guide posts cause the same amount of pressure which thebinding post exerts on theclamping bars below the sheets to be transmitted by the clamping 'bars' to the sheets: In the form illustratedin the drawings, that one of each pair of guide posts which is' further from the rearofthe binder and adjacent the sheets,

is so'pla'ced that the uppermost point of its circumferenceisabout'on alevel with the up- Dermostf point' of the binding post. (See Fig. 2.) I

--These guide posts are telescopic and 'each comprises a pin 22'mounted in one clamping fbar and a cooperating sleeve 23 mounted in thebther clamping ban; The pin and sleeve arepre ferabl'y about equal in length, so "that when telescoped, thepost will occupy practically the entire'jlength ofthe" sleeve, and both are practically aslon'g'asthe dista'nce between the clampin gtjbars when the binder is closed. Thisconstruction gives a; strong bracing to the. bars, For' greater rigidity, thefpin of one ofv each pair of guide posts is mounted on" the clamping which carries the sleeve of the other g'uide post of the pair, as is shown in "Figure Great "strength, rigidity and bracingpower maybe given to'theparallel guide posts by mounting "them asshown in Fig. 3 and Fig. 4. The 'endsof the posts are extendedwell into the "elamoi'nl q bars and a pee; 34 is inserted into "the clamping bar and through ahole 83 in the end of each. 7

In order thatthe sheets niav not have to reston the elements .of the telescopic guide posts or of the binding post. and in order to providea surface which will prevent the sheets in the ledger .from slin'oing when the ledger is onened andsome of thesheets re- 'moyed," platforms ql9 are provided mounted onthe 20. As shownin 2 it may'sometimes be desirable to provide additional guide posts 24: between the. binding 5 post and the pairsof guide posts already de-' scribed? and in such case these additional guidejposts 24 may; also have platforms 19 thereon to provideifurthersupport" for the sheets, These platforms presentflatsurfaces to thesheets, whichsurfac'es may be grooved or E'c'ut' a directionat right-angles to the l n th otth 'e latform. These cutsv serve Since the sheets are not notched .or pervforated it is necessary to provide end closures or guides at each end'of the clamping bars -to keep the sheets 1n reg ster wlth each --other and these also must "be telescopic. As

shown, in the drawings they may consist, at one end at least, of the parts 25 and 26 which are angled extensions of the back plates 18 and are adapted to fit in between the clamping bars and extend across the space between the latter. 'See Fig.2. The outer end closure 26 may suitably have'a groove formed inits edge byv turning .over the lip'27, .in order to guide the end closure 25 into it. I

In machine posting it is desirable to be able to offset laterally, certain sheets'which have had entries made thereon-and to keep those sheets in register and: prevent their :being offset sofar as to fall out oftherack.

To achieve this. result, the end closure at one end of the ledger is made extensible lengthwiseof the clamping bars as shown at 5.. This adjustable end closure may comprise an inner angle bar--28 and an outer angle bar 29pi'nto which the anglebar 28 telescopes when the clamping bars are telescopedfup'on the sheets. Eachpf-zthese; angle bars-has a leg 30 which slides betweenthe clamping bar and the webof the Z-shaped frame piece 16. Each leg30hasfa slot 81 which surrounds the subject of this invention is calculated to receive and hold any sheets whether or not they have notches cuttherein, and that it .is adapted to be simply and efficiently manipulated in posting work and provide a strong grip on the sheets when the ledger is not being worked on.
